Abstract (en)

[origin: US2020411533A1] A memory cell includes a ferroelectric memory transistor, and a select gate transistor which shares a common semiconductor channel, a common source region and a common drain region with the ferroelectric memory transistor. The select gate transistor controls access between the common source region and the common semiconductor channel.
